【 摘 要 】

This study was conducted to determine whether or not mycorrhizal colonization and the growth of maize and oat in andsol field are influenced by reduced tillage. Both crops were grown under four tillage combinations; continuous rotary tillage from previous season, no-tillage followed by rotary tillage, rotary tillage followed by no-tillage and continuous no-tillage from the previous season. The population of AM fungi was not significantly influenced by these tillage treatments. The early-season colonization of AM fungi on corn roots was significantly stimulated by no-tillage treatment, irrespective of preceding tillage treatment. Although the continuous no-tillage treatment enhanced the growth of maize, it had no significant effects on the final yield. On the other hand, none of the tillage treatments had any particular effect on the colonization of AM fungi on oat roots or the growth of the oats. It seems reasonable to conclude that the no-tillage system stimulated colonization of AM fungi and enhanced the early growth of maize, but none of the tillage systems affected the infection with AM fungi of oats roots in this andsol in central Japan.
